  2. Aerosol spray dispenser - Wikipedia

    en.wikipedia.org/wiki/Aerosol_spray_dispenser

    The aerosol spray canister invented by USDA researchers, Lyle Goodhue and William Sullivan. The concepts of aerosol probably go as far back as 1790. [1] The first aerosol spray can patent was granted in Oslo in 1927 to Erik Rotheim, a Norwegian chemical engineer, [1] [2] and a United States patent was granted for the invention in 1931. [3]

  3. Aerosol - Wikipedia

    en.wikipedia.org/wiki/Aerosol

    An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. [1] Aerosols can be generated from natural or human causes. The term aerosol commonly refers to the mixture of particulates in air, and not to the particulate matter alone. [2] Examples of natural aerosols are fog, mist or dust.

  4. Aerosolization - Wikipedia

    en.wikipedia.org/wiki/Aerosolization

    Aerosolization is the process or act of converting some physical substance into the form of particles small and light enough to be carried on the air i.e. into an aerosol. Aerosolization refers to a process of intentionally oxidatively converting and suspending particles or a composition in a moving stream of air for the purpose of delivering ...

  5. Spray nozzle - Wikipedia

    en.wikipedia.org/wiki/Spray_nozzle

    Single-fluid or hydraulic spray nozzles utilize the kinetic energy imparted to the liquid to break it up into droplets. This most widely used type of spray nozzle is more energy efficient at producing surface area than most other types.

  6. Metered-dose inhaler - Wikipedia

    en.wikipedia.org/wiki/Metered-dose_inhaler

    MDI canister and actuator components from H&T Presspart. A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the ...

  7. Nebulizer - Wikipedia

    en.wikipedia.org/wiki/Nebulizer

    The lung deposition characteristics and efficacy of an aerosol depend largely on the particle or droplet size. Generally, the smaller the particle the greater its chance of peripheral penetration and retention. However, for very fine particles below 0.5 μm in diameter there is a chance of avoiding deposition altogether and being exhaled.

  8. Airborne transmission - Wikipedia

    en.wikipedia.org/wiki/Airborne_transmission

    Airborne transmission or aerosol transmission is transmission of an infectious disease through small particles suspended in the air. [2] Infectious diseases capable of airborne transmission include many of considerable importance both in human and veterinary medicine .
